EtherFast Cable/DSL Router with 4-Port Switch

7.I need to set up a server behind my Router.

To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed. Follow these steps to set up port forwarding through the Router’s Web-based Utility. We will be setting up web, ftp, and mail servers.

A.Access the Router’s Web-based Utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Applications & Gaming => Port Range Forwarding tab.

B.Enter any name you want to use for the Application.

C.Enter the port range of the service you are using. For example, if you have a web server, you would enter the range 80 to 80.

D.Select the protocol you will be using, TCP or UDP, or select Both.

E.Enter the IP address of the PC or network device that you want the port server to go to. For example, if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.

F.Check the Enabled option for the port services you want to use. Consider the examples below:

When you have completed the configuration, click the Save Settings button.

8.I need to set up online game hosting or use other Internet applications.

If you want to play online games or use Internet applications, most will work without doing any port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Router to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using. The best way to get the information on what port services to use is to go to the website of the online game or application you want to use. Follow these steps to set up online game hosting or use a certain Internet application:

Cisco Systems BEFSR41 Application Start and End Protocol IP Address Enabled, Need to set up a server behind my Router

BEFSR41 specifications

The Cisco Systems BEFSR41 is a versatile and robust broadband router that has gained popularity for its reliability and feature set, catering to both home users and small businesses. This device integrates an 802.3 Ethernet switch with a wide area network (WAN) port, allowing users to connect multiple local area network (LAN) devices to the internet simultaneously.

One of the standout features of the BEFSR41 is its ability to support up to four Ethernet ports, which facilitates easy connection for computers, printers, and other network devices. This multi-port functionality promotes efficient resource sharing within a network, enabling users to share files, printers, and Internet access seamlessly. The router operates using a robust NAT (Network Address Translation) technology, which enhances network security by ensuring that local IP addresses are not exposed directly to the internet.

The BEFSR41 supports DHCP (Dynamic Host Configuration Protocol), allowing for automatic IP address assignment to connected devices, which simplifies the network setup for users. Furthermore, its built-in firewall features help protect against unauthorized access and potential threats from the internet, making it an ideal choice for small office or home office settings. The router also supports port forwarding, allowing users to configure access for specific applications, such as online gaming or video conferencing.

In terms of connectivity, the BEFSR41 is designed for high-speed broadband connections, making it suitable for DSL or cable internet services. The device offers a straightforward setup process, typically involving a web-based interface that simplifies configuration for users of all technical levels. The compact design and ease of installation make it a convenient choice for those looking to enhance their home or office network.

Additionally, the BEFSR41 supports basic Quality of Service (QoS) features, which enable prioritization of traffic for applications that require higher bandwidth or lower latency. Users can configure these settings to ensure that critical applications receive the necessary resources, promoting a smoother experience during activities like streaming or video calls.

Lastly, the Cisco BEFSR41 is known for its durability and longevity, reflecting the high standards associated with Cisco products. Although newer models and technologies have emerged since its launch, the BEFSR41 remains a solid option for users seeking a reliable and efficient router for basic networking needs. Whether for a small business or a home network, this device offers the essential features and functionality to support daily internet activities.
